Sunstar is the largest O.E.M. supplier of sprockets and brake rotors in the world. In fact, your motorcycle probably came from the factory with a Sunstar sprocket. Need a reason to choose Sunstar? Every Sunstar product is imbued with superior quality, uses an exclusive heat-treatment and quenching process, is based on advanced research and design, and is sold at an added value price.

The evolution of the exclusive Sunstar Z sprocket, now made from the highest quality stainless steel.

Weighs up to 50% lighter than standard steel sprockets.

100% heat treated AND even lighter than before with new weight reduction cut outs, but still has a hardness 5 times that of an aluminum sprocket and twice that of a standard steel sprocket.

Up to 4 times more durable with 1.2 times the lateral strength of any aluminum sprocket.

Great self cleaning capabilities due to the offset tooth design, same as the original Z Sprocket, which extends the life of the entire chain drive system.

It looks pretty cool for a steel sprocket. wanted more longevity out of chain and sprocket setup. the teeth are offset from each other to clean mud out. it is heavier that aluminum. comes with new bolts and nuts
